Design And Implementation Of Inspection Scheme For Cloud Operating System Based On OpenStack

With the development of cloud computing technology,"cloud" has gradually penetrated into all walks of life and become an important part of life.Large-scale cloud platform has a wealth of resources.How to manage and monitor these resources efficiently is very important for the stability of cloud platform.How to better realize the monitoring of the cloud platform has become an important issue that can not be avoided by cloud computing providers.Through the research of OpenStack's characteristics,composition and architecture,based on the analysis of the existing open source cloud resource monitoring system,according to the requirements in the development practice,this paper designs a kind of inspection framework with strong expansibility and low coupling degree.The service modules that need to be checked during the inspection,and the service after the registration is managed by the platform.This not only ensures the scalability of the system,but also can quickly locate the problem location when the system is abnormal,which plays an important role in collaborative development.Aiming at the problem of service discovery and synchronization in distributed system,this paper uses an improved algorithm based on Raft algorithm.This algorithm can effectively reduce the time of next election by adding proxy nodes to Raft algorithm.The improved algorithm can reduce the election time and number of Raft algorithm,and effectively solve the problem of single point failure and overload.Combined with the characteristics of the platform,this paper has completed the monitoring of various physical and virtual resources on cloud platform.After testing,the data of the monitoring system is real and effective,and the alarm information is timely and reasonable,which meets the requirements of cloud platform resource monitoring.
